IMPROVED HAND-PEGG-ING- MACHINE.

The Schedule referred to in these Letters Patent and making part of the Bama Be it known that I, FRANCIS J. VITTUM, of Newburyport, in the State of iYIassachusctts,y have invented certain Improvements in Hand-Pegging Machines, of which the following is a full and exact description.

The obj ect of my invention is to so'construct a handpegging machine, and to so adapt to it a crank-shaft, that, while the machine is held to the work, as it passes over it, with one hand, the movements ofthe awl and peg-driver, and ofthe feeding-devices, are actuated or managed with the other; or, -whilc the shoe is stationary, the machine shall jbe carried over it, and its several parts be actuated by means of a crank and handle.

Prior to my invention and adaptation of the crank, operated by the hand, twenty years skill and invention, (from i834, or thereabouts,) had been vexpended upon hand-peggers, in which the blow given to the awl and peg-driver was imparted by means of a hammer, held in one hand, while the machine was held with the other. After the blow, the bars were elevated by means of springs.

No successful machine was ever constructed inthis manner, to my knowledge. For some reason, either from the effect of the kind oif blow upon the bars, or from the inequality of thc blows given, the machines, by breakages or otherwise, were essentially inoperative.

I conceived the idea. of so constructing, adapting, and

arranging the parts as to elevate the bars, by means of a crank-handle and cam, or ratchet-bar and section of pinion, and to depress them by means of a spring, thus securing greater ease of operation, and greater uniformity oi' blow;tv Many supposed that, the machine beingheld bythe hand upon the work, this mode would'be inoperative, as it would require vthe machine to be held rigidly in its place to resist the reaction oiA the spring, but I found the invention to be a practical success.

So far as the drawings in this application are ccncerned, my improvements are applied to a hand-peggin g machine, invented by E. M. Stevens, and patented, August 6, 1861.

rIhis machine is in some respects more simple than any other. The awl operates as a feeding-instrume'nt, andhis devices for supplyin g the peg-wood are better vthan any I had previously contemplated. My improve* ments, however, can, with equal ease, be applied to any other hand-pegger.

In the drawings, A is the frame; B is a head or stock, 'to the under side of which are aiiixed the pegdriverbarand the awl-bar. The peg-driver barb is a .prolongation of the head B, or it is rigidly attached to it, or it may be pivoted to it. The awl-bar C is pivoted to the head B at c, so as to swing from and tol wards the driver.

D isa flat spring, fastened to the driverbar, at d, and pressing against the awl-bar. Above the head rises a spindle or rod, surrounded with a spiral spring,

I, its top pressing against the frame, and its bottom against the head.

In Figure l, upon the head B, is a pin, F, against which. acts a cam, E, upon a shaft, e, and having a crank-handle, a a. An awl 4is to be inserted in the lower end of the awl-bar, and a peg-driver in the lower end ofthe driver-bar.

The machine being placed with the bars down, as represented by black lines, (the awl in the leather,) and the crank being turned downwards and upwards, the cam It, in rising, acts upon the pin F, and raises the bars to thc position represented in red lines. The spring I is compressed, and, as the cam turns and releases itscll' from the pin F, the pin falls off, and the spring drives down the bars, the awl making a hole, and the driver kdriving a peg.

In the lower part of the awl-bar is a small notch, yn, into which falls the lower end of a cam-shaped dog, G, pivoted to the frame at g, and having a small shoulder, H, on its upper and outer end, striking against a pin, h, in the frame, to prevent its turning up and over too far. I'Vhcn the awl descends, the lower point ot' the dog engages in the notch a in the awl-bar, and, as the bar asccnds, the dog turns, and the awl-bar is crowded back, or, rather, with the awl in the leather, the machine is moved forward on thc work the distance of a peg-hole.

The ibrward edge of the awl-bar, iig. l, is made with such a slant that, on coming down, it will so operate Aon the dog as to engage it in the notch without the use of a spring. v

It is evident that both the awl and driver-hars may be rigidly attached to the head, and rise and fall perpeiulicularly, or they may be so constructed as to rise and fall alternately perpendicularly, in which case the machine is to be fed forward bysome other means.

.A ccntring or feeding-point may be used in advance of the awl, or between the awl and peg-rhiver, which may be operated bythe awl-bar, or piston and spring, or by means of a cam. In my earlier experiments, I used a swinging point in advance of the awl, up to which I moved my machine.

Instead of the cam and pin, I have used a geared rack and cam, or part pinion, as in Figure 2, the rack It appearing on the head, and the pinion lr so arranged that its teeth shall, on the revolution of the crank, take into the teeth of the rack and elevate the bars. As the crank is turned, and the teeth cease to act, the bars fall off, and are driven down by the spring. This may be found preferable on some machines.

What I claim, and desire to secure by Letters Patent, is

and adapted as to its several parts, that, while the machine is held to the work, as it passes over it, witlrone hand, the movements of the awl and pcg-driver, and of l. A hand-pe ggin g machine, so constructed, arranged,

the feeding-devices, shall be actuated or managed with or by means ofthe other', substantially' as described.
